6. Usedexternal image LeD_Lenser_Torch_T7_black%20400.jpg
-Used in semiconductor production, quartz thermometers, laser external image Indium-Gallium-Science-4.jpgdiodes and used to locate tumors.
-Gallium wets glass or porcelain and forms a brilliant mirror when it is painted on glass. It is widely used in doping semiconductors and producing solid-state devices such as transistors.



7. Interesting Facts
external image gallium1.jpg-This element's Melting Point is 29°C. And our body's temperature is 36.5°C. So if we put the Gallium on our hands, then it will be melted.
